Which- Figure 1 is a side elevation of my improved pump. Fig. 2 is avertical section of the same. Fig. 3 is a top view of my improved pump.Fig. 4 is a top view of the bisected collars or rings employed; Fig. 5,an end view of the bisected collars or rings. Fig. 6 is-a view of thepump-head detachedfrom its restingplace upon the air chamber, showingthe han# dle at its extreme elevation and crank depressed, so as toproject below the opening of the pump-head, when it rests or isrotated`upon the top of the air-chamber, for convenience in attaching ordetaching the pump-rod to or from the crank.

In the drawings like parts of the invention are designated by the sameletters of refer- The nature of the present invention con- I sists inimprovements as more fullyv hereinafter described, and will be found torelate to the combination of a revolving pump-head provided with` arock-shaft and nozzle with an 'air-chamber and pun1p-barrel, the objectof the invention being economy of manufacture, increased efficiency ofthe Aair-chamber, and the ability to pass a direct stream of waterthrough the entire pump and out of the noz- To enable those skilled inthe arts to make and use my invention,'I will describe its constructionand operation.

A shows a pump-barrel provided with a I l spout, B, and air-chamber C.The upper por-V tion of the air-chamber C is continued in itsmanufacture, as at c, forming a base or support for thebisected'collar-clamps, and also for the elastic packing.

D shows the pump head, which should be made Water-tight, and which isprovided at its top with the spout E, in line with thevertical axis ofthe pump-barrel A. Within thishead D, upon one side ot' the same, isinserteda rock-shaft, F,to which is attached a crank, f, connected atits lower end to the upper end of the pump-rod g by means of across-bolt, pin,

or any suitable mechanical device for the pur! pose. G is thepump-handle, pinned upon the projecting end of the rock-shaft F. t

H is a packing of rubber orA suitable material, placed directly belowthe baseof the Apump-head 5 and I are bisected collar-clamps, positionupon the continued portion of the air-chamber.

by which the head is retained in its These collar-clamps consist ofplates of metal, which, when brought together, form a square withcircular opening, as clearly shown in Figs. 4 and 5 of the drawings.These plates have a portion of their under side excavated,

within which the lower circular portion of the lpump-head is receivedand rests; andione of these plates has a portion of its ends cutaway toreceive the corresponding projecting ears of the other plate when theplates are brought together into position upon the continued vpor-Vvtion of the air-chamber. These clamps,after being placed in position,are secured therein by means of screws passed through them and into thecontinued portion of the-air-chamber.

J is the plunger, connected to the lower end of the rod. e

Such being the construction, it will be observed that the head may berevolved, so as j f to bring the handle into any desired positionrelative to the spout upon the barrel; that by.l

closing the lower spout by means of cocks,

valves, or screw-caps a direct water-Way is Y afforded through theentire pump to the spout. in the upper portion of the pump 'head, 'andthat by closing this spout in like manner the lower spout is availed offor the exit ot' the water. Thus the pump may be used to pump `waterinto a tank through the upper spout,

while thelower spout is more directly intended` for drawing water or foruse in connection with hose.-

The efficiency of the air-chamber is increased, as the pump-worksheretofore contained in it are 'placed above it and independent of it,

and, from its position directly upon the barrel and between it and thewater-tight head, the tendency of air to leak from the same is lessened.

Economy of manufacture is attained, as the pump-head is more easilyrendered water-tight than air-tight, and the motive power by which therod and plunger are operated are expeditiously connected b v bringingthe head into the position shown in Fig. 6 of the drawings, and thenconnecting the crank upon the rockshaft with the upper end of thepump-rod.

The air-chamber, placed as shown, cannot become exhausted save byabsorption under heavy and continuous pressure of water, and can then beeasily supplied with air by water being allowed to waste itself from thelower
